Description

  The present invention relates to an electric kettle in which a steam passage for conducting steam is formed in a lid, and steam generated in the electric kettle can be discharged from a spout side. It is related with the electric kettle which has the structure which suppressed that temperature detection of this was prevented.

  Electric kettles are widely used as being easy to carry and capable of boiling hot water, coffee, etc. easily. This electric kettle has, for example, a kettle main body having an electric heating part that heats a predetermined amount of water and a power supply base to which an external power cord for supplying electric power to the electric heating part of the electric kettle main body is connected. The kettle body is set on the power supply stand and the power switch is turned on to boil hot water or the like.

  There is also known a configuration in which the lid is detachable from the main body, and the contents are not washed away when the kettle main body is sealed with the lid body and the kettle falls. In such an electric kettle, a structure for discharging the steam generated in the kettle body to the outside at the time of boiling is provided in the lid, and the steam is discharged from a steam port provided in the upper part of the lid. ing. For example, a steam hole for discharging steam to the outside is formed in the upper surface of the lid of the electric kettle disclosed in Patent Document 1 below, and a steam passage for guiding the steam to the steam hole in the lid Is formed.

  For example, in the electric kettle described in Patent Document 1 below, an apparatus for boiling water with a heater, a lid for the apparatus, a handle provided around the exterior of the apparatus, and steam generated in the apparatus are introduced. In a handy type electric kettle equipped with a sensor chamber at the upper part of the handle to be in contact with the steam sensor, the sensor chamber is branched from the middle of the steam path for introducing and discharging steam into the upper part of the handle from the container side, and the steam path Steam that branches and flows into the sensor chamber comes into contact with the steam sensor, and extends from the steam passage to the sensor chamber at a branch point upstream of the steam passage between the steam passage and the sensor chamber. In order to restrict the inflow region, a partition wall that partially partitions the steam passage side and the sensor chamber side is provided.

  By adopting such a configuration, according to the electric kettle described in Patent Document 1 below, the lid allows the steam generated from the vessel body to be discharged to the outside while limiting the position and range when boiling, A part of the steam generated in the container flows into the steam path on the handle side from the container side and is discharged by the steam pressure generated by the restriction of discharge, and also flows into the sensor chamber branched from the steam path. When in contact with the steam sensor to detect boiling, the partition wall that extends toward the downstream side of the steam passage is regulated at the branch point on the upstream side of the steam passage between the steam passage and the sensor chamber. However, since an appropriate amount of water is allowed to flow into the sensor chamber from the deviated range that leaves the partition area, the condensed water does not become excessive and flows back into the sensor chamber while smoothly returning to the steam passage without antagonizing the inflowing steam. While providing flow gas to go around the counter-offset side, the new steam can be successively into contact with the vapor sensor. For this reason, the newest temperature in an electric kettle can be measured correctly.

JP 2009-291418 A

  In the electric kettle described in Patent Document 1, the steam generated inside the kettle is efficiently guided to the steam sensor through the steam passage, and the steam is discharged from the rear part of the lid body away from the extraction port and the operation part of the lid body.

  Next, the lid will be described with reference to FIGS. As shown in FIGS. 2 and 3, the lid body 28 includes an intermediate plate 29, an outer peripheral wall 30 having a predetermined height extending in the vertical direction around the intermediate plate 29, and an upper portion of the outer peripheral wall 30. And an inner lid 32 having a plurality of holes to be attached below the outer peripheral wall 30. The outer peripheral wall 30 has a water inlet 33 for injecting the liquid in the container 19 of the kettle main body 11 into the spout 20, and a steam generated in the kettle main body 11 on the opposite side of the water inlet 33. A steam port 34 for leading to the steam sensor 24 in 23 is formed. The lid is formed with an opening / closing operation member 54 of the opening / closing mechanism 53 and a pair of knob members 37a, 37b of the attachment / detachment mechanism 50, and a part of the upper lid is opened so that these can be operated from the upper lid. Further, a portion of the top lid 31 corresponding to the spout 20 formed so as to cover the spout 20 formed in the kettle body 11 and a portion corresponding to the spout 20 of the middle plate 29 of the lid 28 Is formed to extend. Further, a liquid supply path 36 that guides the liquid in the container 19 to the spout 20 and a liquid supply port 35 that connects the liquid supply path 36 and the container 19 are provided in a portion adjacent to the spout 20 of the lid 28. The details are described later.

  Between the intermediate plate 29 and the outer peripheral wall 30, a steam valve chamber 39 is provided in which a steam conduction port 45 serving as a passage for steam generated in the container 19 is formed. In addition, a steam passage 40 having an intermediate plate 29 as a ceiling is formed inside the lid body 28, and this steam passage 40 is connected to the first steam passage 40 a communicating with the spout 20 of the kettle body 11 and the lid body 28.

The on-off valve 57 is formed to have a size that can close the liquid supply port 35 of the lid 28, and a protrusion that contacts the contact portion of the on-off valve pushing portion 56 at the substantially central portion of the on-off valve 57. 58 is formed. Then, by moving the opening / closing operation member 54 back and forth, the contact portion of the opening / closing valve pushing portion 56 formed in a tapered shape moves the protrusion 58 of the opening / closing valve 57 up and down along the taper angle. The liquid supply port 35 can be opened and closed. Further, the on-off valve 57 moves downward, so that the spring 59 is compressed.

  When the liquid in the container 19 is poured, the opening / closing operation member 54 is moved to the spout 20 side, so that the taper of the contact portion of the opening / closing valve pushing portion 56 pushes down the projection 58 of the opening / closing valve 57 to open / close the liquid. Accordingly, the valve 57 moves downward, the liquid supply port 35 is opened, and the liquid can flow to the liquid supply path 36. Further, after use, the opening / closing mechanism 53 is moved to the opposite side to the direction moved when the opening / closing operation member 54 is poured, the opening / closing valve pushing portion 56 is moved, and the taper of the contact portion is the protrusion of the opening / closing valve 57.

  Next, the steam passage 40 formed inside the lid 28 will be described. As shown in FIGS. 2 to 4, the steam passage 40 is a portion that conducts steam generated in the container 19, and discharges the steam to the outside and guides it to the steam sensor 24.

  The steam passage 40 is formed with the intermediate plate 29 formed inside the lid body 28 as a ceiling portion 41, a member 43 a provided with a liquid leakage prevention mechanism 43 as a bottom surface, and the outer peripheral wall 30 of the lid body 28 as a side surface. Yes. The steam passage 40 is formed by a first steam passage 40a and a second steam passage 40b, and the first steam passage 40a is in communication with a liquid supply passage 36 that is in communication with the water injection port 33 of the lid body 28. The steam passage 40 b communicates with the steam port 34 of the lid 28 and the opening 21 of the kettle body 11 so that the steam is guided to the steam sensor 24 provided in the handle portion 23 of the kettle body 11.

  Further, between the first vapor passage 40a and the liquid supply passage 36, a portion of the middle plate 29 of the lid 28 between the first vapor passage 40a and the liquid supply passage 36 has an inner lid with a predetermined size. A cylindrical communication hole 42 through which the first vapor passage 40a and the liquid supply passage 36 are communicated is formed at the center of the protruding portion. The cross section of the communication hole 42 may be rectangular, circular, or elliptical, or may be other shapes.

  Here, the flow of the steam will be described. When the liquid in the container 19 is boiled, the liquid supply port 35 is closed by an on-off valve 57. Then, when the liquid in the container 19 boils and vapor is generated, the vapor passes through the vapor valve chamber 39 and is guided from the vapor conduction port 45 to the respective vapor passages 40. Thereafter, in the second steam passage 40b, a part of the steam passes through the steam port 34 of the lid 28 and the opening 21 of the kettle body 11, reaches the steam sensor 24, and the steam temperature is detected. On the other hand, the other vapor passes through the first vapor passage 40 a, the communication hole 42, and is guided to the liquid supply passage 36. The steam guided to the liquid supply path 36 passes through the water inlet 33 of the lid 28 and is discharged to the outside from the spout 20 of the kettle body 11. By doing in this way, there is less possibility that the user will accidentally touch the steam, and safety can be improved.

  On the other hand, when pouring liquid, the open / close valve 57 is moved downward by the open / close mechanism 53 to open the liquid supply port 35. Then, by gripping the handle 23 and tilting the kettle 10, the liquid in the container 19 is guided from the liquid supply port 35 to the liquid supply path 36, and then passes through the water injection port 33 of the lid 28, Liquid can be poured from the spout 20 of the kettle body 11. In addition, when pouring liquid, boiling has already ended, but generation of vapor may continue. However, even in this state, since the steam is discharged from the spout 20 to the outside, the same safety as when boiling is obtained.

  Here, after pouring the liquid, when the kettle 10 is returned to a predetermined position, the liquid remaining in the spout 20 and the liquid supply path 36 is returned from the liquid supply port 35 into the container 19. When the on-off valve 57 is closed with the vigorous return or the kettle 10 tilted, a large amount of liquid passes through the liquid supply port 35, passes through the communication hole 42, and enters the first vapor passage 40a. A case occurs. Then, the liquid that has entered the second vapor passage 40b may block the vapor port 34 of the lid 28 or the opening 21 of the kettle body 11. Further, the liquid may adhere to the vapor sensor 24. When such a state occurs, the vapor sensor 24 cannot detect the vapor temperature, cannot accurately measure the temperature of the liquid in the container 19, and further, the temperature cannot be detected, so that the liquid boils. There is also a risk of continuing or flying.

Therefore, in the kettle of the first embodiment, as shown in FIG. 4, the height of the steam port 34 is higher than the height of the ceiling portion 41 of the first steam passage 40 a. By doing so, it becomes difficult for the liquid that has flowed back to reach the vapor port 34. Therefore, even if a large amount of liquid enters the second vapor passage 40b, the vapor port 34 can be prevented from being blocked by the liquid. In FIG. 4, the gap g is formed so that there is a difference, but the steam port 34 only needs to be formed higher than the height of the ceiling 41 of the first steam passage 40 a. Moreover, the height of the ceiling part 41 of the first steam passage 40a and the steam port 34 may be the same.
[Embodiment 2]
Next, the kettle according to the second embodiment will be described. The kettle according to the first embodiment has been described with respect to the case where the height of the steam port is formed higher than that of the first steam passage in order to suppress the liquid from entering the steam port. A case where the size of the cross section of the first steam passage is made smaller than the size of the cross section will be described. Note that the kettle according to the second embodiment is different from the kettle according to the first embodiment only in the structure of the first steam passage.

  As shown in FIG. 5, the kettle according to the second embodiment has a communication hole 42 in which the liquid supply passage 36 and the first vapor passage 40 a have the narrowest cross-sectional sizes so that the liquid does not easily flow back into the vapor passage 40. The cross-sectional size A1 is formed to be smaller than the cross-sectional size A2 of the steam port 34 (A1 <A2). By doing so, the size of the cross section of the communication hole 42 having the narrowest cross section of the first vapor passage 40a connected to the liquid supply path 36 is formed smaller than the size of the cross section of the vapor port 34. Since it is difficult for the liquid to flow backward from the first vapor passage 40a and the amount of the liquid flowing backward is not so large as to block the vapor port 34, it is possible to prevent the vapor port 34 from being blocked.

  In addition, although the cross-sectional size of the steam port 34 was compared with the cross-sectional size of the communication hole 42, the cross-sectional size of the narrowest portion of the first steam passage 40 a is not limited to this. What is necessary is just to form so that it may become smaller than the magnitude | size of this.
